• Set the span values, p6 and p7, within the

measurement range indicated on page 5-8.

• Input values within 6 digits disregarding the

decimal point for p6 and p7. The decimal point

position is fixed to the decimal point position of

the setting range of page 5-8.

• The measurement range cannot be changed while

executing a report.

• The measurement range cannot be changed while

executing a report or computation, or when a file

is written.

Setting the strain input(DR232/DR242)

Setting SRp1, p2, p3, p4, p5<terminator>

p1 Channel number (001 to 560)

p2 STRAIN

p3 Measurement range

2k/20k/200k

p4 Left value of span

p5 Right value of span

Example Set the measurement range of subunit 1 and channel

01 to 20k, left value of span to 0, and right value of

span to 100.

SR101, STRAIN, 20k, 0, 100

Comments • Even when the settings of p3 are the same

parameters, the measurement range of the strain

varies depending on the gauge method. For

details, refer to page 5-9.

• Set spans, p4 and p5, within the measurement

range indicated in page 5-9.

• Input values within 6 digits disregarding the

decimal point for p4 and p5.

• The measurement range cannot be changed while

executing a report or compuration, or when a file

is written.

Setting the pulse input(DR232/DR242)

Setting SRp1, p2, p3, p4, p5, p6, p7, p8, p9<terminator>

p1 Channel number (001 to 560)

p2 PULSE

p3 Measuring mode

RATE momentary pulse count mode

GATE contact ON/OFF detection mode

p4 Left value of span (0 to 30000)

p5 Right value of span (0 to 30000)

p6 Left value of scale (0 to 30000)

p7 Right value of scale (0 to 30000)

p8 Decimal point position of scale (0 to 4)

p9 Filter (ON or OFF)

Example Set subunit 1 and channel 01 to momentary pulse

count mode, left value of span to 0, and right value

of span to 1000.

SR101, PULSE, RATE, 0, 1000, 0, 1000, 0

Comments • When omitting p6, p7, or p8, omit all three.

• When summing the count number or the ON time,

set the computational expression with the SO

command, then execute computation start with the

EX command. When the pulse input module is

installed, the use of computation channels become

available without the math option. However, the

only computational expression available in this

case is TLOG.PSUM(XXX) for summing the

count number or the ON time.

• The measurement range cannot be changed while

executing a report or computation, or when a file

is written.

1 V is converted to 0.00 and 5 V to 100.00.

SR002, SCL, VOLT, 6V, 1000, 5000, 0, 10000, 2

Comments • For the p4 measurement range, see the range

parameter table on Pages 5-7 and 5-8.

• For the p5 and p6 setting spans, set them in the

ranges shown in the setting range on Pages 5-7

and 5-8.

• For p5 and p6 setting values, enter them within 6

digits excluding the decimal point.

• Select either to set all three parameters, p7, p8 and

p9, or to omit them all.

• The measurement range cannot be changed while

executing a report or computation, or when a file

is written.

Comments • Settings of p4 and p5 are common within one

power monitor module. If the setting is changed,

the settings on other channels also change.
